REGULATOR FOR HEATERS.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed March 6, 1906. Serial No. 304,459.

To all whom rt may concern:

Be it known that I, GARRETT W. HAGAMAN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Regulators for Heaters; and 1- do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to an improved regulator for controlling the drafts in furnaces and relates more particularly to an arrangement of this kind that is de signed to increase the draft and quicken the fire in a heater, at a predetermined time.

A further object of the invention is to provide a device of this kind that can be regulated and set so that the drafts will be opened when the time arrived.

A further object is to provide means for accomplishing this purpose, these means being situated on the lever of the usual form of damper regulator and acting in conjunction with a fixed rod or stop on the body of the heater. 1 x

The invention illustrated in the accompanying drawings in which,

Figure 1 illustrates a heater with my improved attachment. Fig. 2 is a face view of the feeding door of the heater. Fig. 3 is a detail of the clock used in the device, being partly broken away, and Fig. 4 is a top view of this clock.

In the drawings 10 is the usual heater being provided with a damper regulator 11 of any well'known form which is provided with the lever 12 and the weight 13, all this tending through the chain 13, lever 14 and chain 15 to regulate the drafts in the heater 10, whereby when the steam pressure is high the drafts will be shut, and when the steam pressure is low the drafts will be opened. I also regulate by means of the chain 16, the slides 17, in the front door 18 of the heater, when the drafts are closed these slides being open.

At a suitable point on the lever 12,.1 place a clock 19 provided with a lock-plate 20, and a fixed rod 21 is arranged on the heater and provided with the dependent rod 22 which holds the lever 12 down in the position shown'in Fig. 1 against the influence of the weight 13 by engaging the lock-plate 20.

Referring to Fig. 3, it will be seen that a usual clock mechanism 23 is used for this purpose, and the lockplate 20 is pivoted as at 24 and held up in its position by means of the spring 25. An arm 26 provided with a roller 27 locks this stop 20 by engaging with the lever 28, which lever is fast as 29, and is perforated to permit it to straddle the shaft 31 at 30. The shaft 31 regulates the release of the stop 20 by means of the arm 32, which,

when the wheel 33 is revolved by the clock Work to a certain point, drops into the detent 34 of the cam 35. It will thus be seen that while the shaft 31 is fixed against longitudinal movement, the cam 35 and the wheel to which it is attached, which wheel is connected with the clock train, can slide along the shaft 31 so that when the cam 35 arrives with its detent 34 opposite the arm 32, it will snap over into place, this being caused by the locking piece 28 which is made of spring metal, and tends to constantly move the cam 35. When the arm 28 springs over, as before described, it releases the roller 27, on the bar 26, and the locking plate 20 can be pressed down. When this occurs, the weight 13, on the end of the damper lever 12, forces the other end of the lever and consequently the clock upward, and the locking lever slides off the plate 20, and there is no interference with the normal action of the damper regulator. To make the action of the rod that engages the lock-plate easy, after the clockplate is released, the rod is provided with a roller 36 on its end, and this roller reduces any friction and allows the tripping of the damper lever without any hindrance. The roller 36 is preferably secured on the end of a rod 38 which can slide in the bar 22, and is fastened in any desired position by the set-screw 37.

This apparatus can be used the same as an alarm clock, so that after the dampers are all closed and the lever 12 locked, the shaft 31 can be turned by a key, so that the fire will be made to burn by an opening of the dampers at a set time. This is particularly desirable when a fire is banked over night.

The particular location of the clock on the shaft 12, and of the locking arm 22 can be varied at will, and altered to suit particular styles of furnaces or heaters.

Having thus described my invention, what I claim is:

1. An apparatus of the kind described comprising; a lever 01 a damper regulator, having a weight on one side of its pivot and a clock on the other side, a lock-plate on the clock, a rod secured to the heater and engaging the lockplate, and means in the clock for releasing the locl plate.

2. An apparatus of the kind described comprising a pivoted lever of a damper regulator, having a weight on one side of its pivot and a clock on the other side, a lockplate on the clock, a pivoted lever on the heater adapted to engage the locl plate to lock the lever of the damper, and meansin the clock for releasing the lock-plate.

3. An apparatus of the kind described, comprising a pivoted lever of a damper regulator, a clock on the end of the lever opposed to the weight, a lock-plate on the clock, a lever pivoted on the heater and adjustable as to its length arranged to engage the lock-plate on the clock, means in the clock for releasing the lock-plate, and means for regulating the releasing means.

In testimony, that I claim the foregoing, I have here unto set my hand this 23d day of February, 1900.
